- The first of three Audi concepts with the suffix “sphere” will be the rear-wheel-drive electric convertible concept known as the Audi Skysphere.
Even the interior is altered, with the pedals and steering wheel emerging from the bulkhead as the passenger seat is moved back and the instrument panel part of the driver’s dash is brought forward. It is, in fact, a transformer.

Premium mobility redefined
The first of a line of Audi concept cars is the skysphere concept1. The vehicles were created with the sole intention of creating an interactive space and experience device for the future of transportation. The electric two-door roadster blends the idea of automated2 driving with a completely connected digital ecosystem and a brand-new interior design.
Highlights from the World Premiere of the Audi skysphere concept1
The intriguing confluence of design and experience that is the Audi skysphere idea was created through both virtual and actual interaction between the designers and developers in Ingolstadt and the Audi Design Loft in Malibu, California. The “Celebration of Progress” now combines both worlds. View the presentation of the first of three new concept cars from the brand by Hildegard Wortmann, Member of the Board of Management, Henrik Wenders, Head of Brand AUDI AG, and Gael Buzyn, Senior Director of the Audi Design Loft in Malibu.
From idea to concept car: how the Audi skysphere concept1 came about
The Audi skysphere concept1 was developed using a combination of conventional and digital design. The documentation provides details on the innovative interior design and engineering of a concept car that is both a sports car and a sedan, and it demonstrates how 3D technology was used to advance the design process, which was carried out over a distance of thousands of miles between the Audi Design Loft in Malibu and the team in Ingolstadt, Germany.
The Audi Skysphere has a top speed of.
The 1931 Horch 853, an Audi ancestor that was a long, opulent roadster with a small interior, served as inspiration for the proportions and function of Gael Buzyn and the team at the Audi Design Studio in Malibu when they created the Skysphere concept. Both vehicles also have rear-wheel drive, but unlike the straight-eight-powered Horch, the Skysphere concept has an electric motor with 623 horsepower and a battery pack, with 30% of the battery pack located between the passengers and the remaining 70% behind the rear bulkhead, resulting in a 40:60 front to rear weight distribution. According to Audi, the Skysphere has enough theoretical propulsion to reach 62 mph in 4.0 seconds with a single speed and 553 pound-feet of torque.
The Audi Skysphere uses electricity.
The issue with modern vehicles, according to this Audi, is that they don’t make enough references to classic children’s cartoons from the 1980s. The Transformers, specifically. This brand-new idea seeks to fix that.
This two-seater totally electric concept car, officially known as the Audi “skysphere” (no capitalization), aesthetically mimics the company’s own Horch 853 roadster from the 1930s with a long bonnet and a compact cabin. though beneath? complete transformer
It can figuratively adjust the length of its wheelbase and body by 250mm with the stroke of a button, which explains this. It is one of the vehicle’s two driving modes; in ‘Sports’ mode, the vehicle measures 4.94m in length, lowers its ride height by 10mm, and switches to rear-wheel steering for maximum helmsmanship.
However, while in “Grand Touring” mode, electric motors linked to a “sophisticated” mechanism lengthen the wheelbase to 5.19 meters and relocate the pedals and steering wheel to a “invisible location to maximize interior space. Yes, of course.
The Audi Skysphere has a roof, right?
The two-roof door’s retracts, just like any decent roadster. However, this is where the engineering team at Audi pulled off a nice trick. Skysphere is around 194 inches long when used as a roadster. Additionally, it should be able to maneuver nimbly around corners thanks to its low-mounted two-part battery pack and motors.
A single electric engine powers the display car’s rear wheels with 623 horsepower and 553 pound-feet of torque. According to Audi, it will take just 4 seconds to accelerate the nearly 4,000-pound skysphere from 0 to 60 mph.
But when the excitement is over and you want to take a relaxing sail, Skysphere changes into a mobile lounge. As the body and frame parts separate, the wheelbase increases to 204 inches from nose to tail, a distance of about a foot. The prototype is currently functioning at Level 4 autonomy as the conventional driver controls disappear at the same time. That implies that it can travel at any time and anywhere without ever requiring a driver.
What are the benefits of the WLTP cycle over the prior NEDC cycle in the case of Audi?
For more than 20 years, the New European Driving Cycle has been used to calculate the consumption and emission levels of passenger cars (NEDC). The existing measurement method will be replaced starting in September 2017 by the WLTP (Worldwide Harmonized Light Duty Test Procedure). The objective is to show data more realistically to reflect the new driving and traffic situations in Europe. At the same time, real-world emissions from driving must be measured (RDE = Real Driving Emissions). Additionally, the new Euro 6c emission standard is becoming effective.
a new driving cycle for Europe (NEDC) The New European Driving Cycle, or NEDC, has served as the foundation for calculating car emission limits in the European Union since the adoption of the unified European emissions laws in 1996. NEDC was created in the 1990s by the EU Commission and the UN Economic Commission for Europe (UNECE) with the intention of giving European consumers and policymakers a common standard. It serves as the foundation for establishing official consumption levels and CO2 emissions from passenger automobiles and light commercial vehicles, as well as for providing evidence of compliance with the regulatory limitations on pollutants. The NEDC is also used to calculate the electrical driving range of plug-in hybrid and electric vehicle models.
The NEDC is conducted on a dynamometer and is split into two parts: following a cold start of the engine, 13 minutes of urban driving simulation are conducted, including frequent accelerating and braking as well as periods of stopping. 18.8 km/h (11.7 mph) is the cycle’s average speed, which is roughly similar to commuter traffic conditions. Then, for the next 400 seconds, a simulation of intercity driving occurs, with the car reaching a top speed of 120 km/h (74.6 mph). The test mass in the form of flywheel mass categories, the driving resistance, and the shift points (in the event of a manual transmission) are accurately established throughout the measurement.
As of September 1, 2015, the impact of specialized equipment or electrical consumers is still disregarded while the rolling resistance of the tires is taken into account. The NEDC details the measurement and environmental circumstances in addition to the driving profile. It details details such as the temperatures at which the measurement is to take place and how a vehicle is to be loaded during the measurement. The measurement results can be objectively compared thanks to this consistent definition of the measuring conditions.
Road traffic may deviate from the NEDC list of values since standardized test cycles like the NEDC only partially reflect the range of potential operational situations and various driving profiles. Additionally, the NEDC does not consider conditions like an air conditioning system that is turned on, other consumers that are switched on, or a specific vehicle’s configuration with optional equipment.
WLTP The WLTP (Worldwide Harmonized Light Duty Test Procedure) will replace the NEDC as the method for calculating consumption levels on September 1, 2017. WLTP portrays emission levels and fuel consumption rates more realistically than previous test methods and is designed to be a standardized test procedure for passenger automobiles and light commercial vehicles. The EU Member States will receive a matching recommendation in late May 2017; it will be put into effect legally and become enforceable for tax purposes no later than in 2018. Customers’ taxes will continue to be calculated using the NEDC values (or the NEDC values derived with the WLTP measurement) throughout the transitional phase between September 1, 2017, and January 1, 2019 (country-specific variances are likely).
The WLTP is substantially more dynamic than the NEDC, with four stages of acceleration and braking events up to 60, 80, 100, and 130 km/h (37.3, 49.7, 62.1, and 80.8 mph) in its prescribed driving profiles. As a result, several driving scenarios, including motorway and urban driving, are depicted. 131 km/h (81.4 mph) is the top speed in the WLTP driving cycle, which is 10 km/h (6.2 mph) faster than it is in the NEDC. The new test cycle is longer than the old one by 30 minutes and has a faster average speed (46.6 km/h [29.0 mph]). Instead of the previous 11 kilometers (6.8 miles), the circuit traveled on the dynamometer now measures around 23 kilometers (14.3 miles), and the test chamber’s temperature is 23C. (73.4F).
The Ambient Temperature Correction Test, as required by the EU, accounts for the impact on consumption of a vehicle parked for more than nine hours at an average ambient temperature of 14C (57.2F).
The effects of customer-specific optional equipment on weight, aerodynamics, and electrical system power consumption are taken into account by WLTP (quiescent current). As before with the NEDC, comfort consumers like the air conditioning and seat heating are turned off during the measurement.
The shift points (for manual transmissions) have also undergone changes. They are no longer statically stated, but rather estimated based on factors related to the vehicle, such as the engine power and transmission gear ratio.
On September 1, 2017, and on September 1, 2018, all new type-approved engines and models must have their WLTP emissions and consumption levels checked.
The measures RDE and PEMS Real Driving Emissions is referred to as RDE. As of September 1, 2017, emission tests under actual traffic circumstances are necessary in Europe in addition to the new WLTP test cycle on the dynamometer. With the help of portable emissions measurement systems (PEMS), the RDE test procedure is carried out. The PEMS measurement box, which is connected to the vehicle’s exhaust system, measures the nitrogen oxide and carbon monoxide emissions as well as a number of engine, vehicle, and environmental parameters along the predetermined route. There is then a precise correlation between driving conditions and exhaust characteristics as a result of the ongoing comparison against GPS data.
The trip time for an RDE measurement is between 90 and 120 minutes, depending on traffic and driving style, and the route comprises several arbitrary acceleration and braking occurrences. The maximum amount by which the gaseous emissions detected on the road may exceed the value established in the WLTP procedure under laboratory conditions is indicated by the compliance factor (CF). The first stage will have a CF of 2.1 for NOx emissions and 1.5 for the PN during a transitional period that starts in September 2017. (particulate number). The factor will be set at a maximum of 1.5 in the second stage, which will start in January 2020.
The complex thermal behavior of the combustion engine is not taken into consideration by the RDE measurement. Depending on the operating mode, different levels of consumption and emissions occur. For instance, they will be higher at full load and during a cold start than after the engine has warmed up and the vehicle is cruising through traffic. The findings of the measurement are also strongly influenced by the driving habits of the individual. A CF of 2.1 is challenging to achieve since the conformance factor takes the dispersion caused by the measurement boundary circumstances into account. Gasoline engines need to have particulate filters installed in order to meet the new standards. Their implementation at Audi is planned to begin with the Audi A5 Coup 2.0 TFSI in June 2017 and be gradually expanded to all other series after that. Audi will start measuring consumption and emissions using spark ignition engine particulate filters in the future in order to comply with RDE regulations.
new Euro 6c emission requirements Since its implementation in 1991, the European emission standard has gradually lowered the caps on emissions from vehicles and trucks. Diesel engines and spark ignition are subject to different restrictions. The so-called restricted exhaust components, like nitrogen oxide (NOx) emissions and particle emissions, are regulated.
For newly type-approved vehicles, the Euro 6c standard will take effect on September 1, 2017, and for newly registered vehicles, it will take effect on September 1, 2018. The particle number (PN) for spark ignition engines is the most significant difference compared to the existing Euro 6b standard, followed by the conversion from NEDC to the WLTP method and RDE tests. It may not rise above one-tenth of the former value in the future. As Euro 6c is implemented, the threshold values for on-board diagnostic systems will become more stringent (OBD). The driver still has the biggest impact on fuel economy through his or her own driving habits.

A prototype automobile is what?
A concept automobile is a vehicle designed to display novel aesthetics and/or novel technology. It is also referred to as a concept vehicle, show vehicle, or prototype. They are frequently displayed at car shows to see how consumers react to novel and radical designs that might or might not be built in large quantities. The concept automobile is largely credited to designer Harley Earl of General Motors, who also did much to publicize it through its 1950s traveling Motorama displays.
Concept automobiles are never immediately put into production. In the modern day, each aspect would go through a number of revisions before the design was finalized in order to account for cost, practicality, safety, and regulatory compliance. Instead of a concept car, a prototype with “production-intent” accomplishes this. [1]
Why aren’t there any convertible electric cars?
The incentive for automakers to develop a convertible car with an all-electric or hybrid motor has decreased for reasons other than cultural trends. There are also technical factors at work. Specs are everything.
Vehicles fueled by electricity in general are heavier than those using conventional gas engines. Their heavier battery packs and electric motor systems are the cause of this higher curb weight.
Additionally, convertibles with a hard top or a soft top have always weighed more than those with a fixed roof.
Engineers must therefore add weight to a car that is already heavy when designing an electric convertible.
Electric car powertrains have undergone decades of research to become viable and effective on today’s roadways. However, engineers have yet to produce in large quantities an electric convertible that appeals to modern drivers and is effective enough to fulfill all of the drivers’ desires for an electric vehicle.
